Disposal wells can be applied in IRIS through:
The following are processes for each application above.
Apply for a disposal well licence:
- Determine whether a prior authorization is required for the disposal wells.
- As outlined in Directive PNG008, the prior authorization is required before a well licence submission for:
- An acid gas disposal well as part of an acid gas disposal project;
- A waste disposal well as part of a geothermal project; or
- If the proposed disposal pool is a commingled pool.
- Log in to IRIS and complete the well licence application and attach the required documents.
Note: An application for a disposal well licence is either a routine or non-routine application in IRIS depending on the type of well and the declarations made by the applicant. A non-routine application is triggered when:
- Well completion type as potash waste disposal well, waste disposal well, or acid gas disposal well;
- If the proposed disposal pool is a commingled pool; and/or
- Declarations not meeting routine application requirements.
Apply for reclassification or recompletion to a disposal well:
Reclassification and/or recompletion to a disposal well after the initial completion of the well must be applied for in IRIS, using the appropriate application process. Refer to Guideline PNG024: Reclassification and Recompletion and Apply to Reclassify and Complete a Well.
- Determine whether the disposal well is part of a project (i.e., acid gas disposal, or geothermal project).
- Complete the appropriate Reclassification or Recompletion Form and include necessary attachments:
- Log in to IRIS and complete the appropriate application process for authorization and attach the required documents.
Note: A well licence application instead of reclassification/recompletion application must be made in IRIS, if:
- Re-enter an abandoned well;
- Deepen a non-abandoned well into another stratigraphic unit; or
- Change the trajectory of a non-abandoned well (e.g., from horizontal to vertical or vertical to horizontal).
Apply for commingled disposal (when the well is not part of a project):
If the disposal well is not part of a project and is used for commingled disposal, a commingling application must be made and authorized by the ministry before licensing or reclassifying/recompleting the well. To apply:
- Determine whether the proposed pool is a commingled pool and the well is not part of a project.
- Complete the Application to Commingle Disposal Form, and include all required attachments (see the "Form Instructions" tab of the application).
- Log in to IRIS and complete the appropriate application process for authorization and attach the required documents.
Apply for an acid gas disposal well as part of an acid gas disposal project:
An acid gas disposal project means a development that groups one or more wells for approval of the disposal of acid gas into a deep saline aquifer or depleted hydrocarbon pool in non-EOR operations. An acid gas disposal project application must be made and authorized by the ministry before licensing or reclassifying/recompleting an acid gas disposal well. A separate Reclassification/Recompletion application or Commingling application is not required that can be authorized as part of an acid gas project application. To apply for an acid gas disposal project:
- Complete the Application for Acid Gas Disposal Project Form and include all required attachments. If applicable, a separate well licence application must be submitted after receiving the project authorization. See the Form Instructions tab of the application.
- Complete the Public Notice Process if required.
- Obtain written consent to the project from all Freehold mineral owners within the drainage area of the proposed disposal well(s).
- Complete the Reclassification/Recompletion (as part of a reservoir application) Form with all the necessary attachments (as one document), if required. For more information, see Guideline PNG024.
- Confirm that all the information is complete and accurate, and forms are dated and signed. Ensure all required attachments are included:
- Application for Acid Gas Disposal Project Form and attachments.
- Well list
- Completed Public Notice Process package, documented objections and required consents as a separate document, if applicable.
- Reclassification/Recompletion (as part of a reservoir application) Form with all the necessary attachments.
- Third-party Engineering Report (Confidential)
- Seismic Data and Report (Confidential)
- Other supporting documents (if applicable)
- Log in to IRIS and complete the appropriate application process for authorization and attach the required documents.
If applicable, a separate well licence application must be submitted after receiving the project authorization.
If applicable, a separate well licence application must be submitted after receiving the project authorization.
Apply for a waste disposal well as part of a geothermal project:
A geothermal project means a development that geothermal fluids are produced from a water source well, the geothermal energy is recovered at surface as part of an industrial process for any purpose, and the cooling fluids are disposed into subsurface through a waste disposal well.
A geothermal project application must be made and authorized by the ministry before licensing or reclassifying/recompleting a waste disposal well as part of geothermal project. A separate Reclassification/Recompletion application or Commingling application is not required that can be authorized as part of a geothermal project application.
Please refer to Apply for a Geothermal Project for information on requirements and application process for a geothermal project.
If applicable, a separate well licence application must be submitted after receiving the project authorization.
